5A CT 3 Phase 4 Wire Active & Reactive Din Rail Energy Meter /
Electric Meter for AMR System
Product Description
Model YEM421AC three phase four wire electronic DIN rail active and
reactive integration energy meter is a kind of new style three
phase four wire active and reactive energy meter, it adopt
micro-electronics technique, and imported large scale integrate
circuit, use advanced technique of digital and SMT techniques, etc.
The meter completely accord with relevant technical requirements of
class 1 three phase active energy meter stipulated in international
standard IEC 62053-21 and class 2 three phase reactive energy meter
stipulated in international standard IEC 62053-23. It can accurate
and directly measure 50Hz or 60Hz active and reactive energy
consumption from three phase four wire AC electricity net, it can
display total energy consumption by step motor type impulse
register. This meter has seven digits LCD displays shows active
energy. And there are far infrared and RS485 communication module
in it. Contact with all kind of AMR system conveniently. It has
following features: good reliability, small volume, light weight,
specious nice appearance, convenient installation, etc.

Competitive Advantage
1. 35mm standard DIN rail installation, complying with standard DIN
EN50022. Or front board installed (mounting holes center distance
63 mm), users can choose any one by themselves.
2. Ten pole width (Modulus 12.5mm), complying with standard
JB/T7121-1993.
3. Type S wiring (Inlet from bottom, outlet from top), use CT
connect operation, may select 27 CT ratio, the meter will read
directly after set, and needn’t multiplied by CT rate.
4. 7 digits LCD display, 5+2 digits(99999.91kWh,Only when CT ratio
5:5A) or 7 digits display. It is choose by the CT ratio which is
set.
5. Standard configuration one port of active pulse output passive
and one port of reactive pulse output passive(polarity),The output
rate are 0.01, 0.1, 1, 10kWh or kvarh/Pulse. Users can choose any
one by themselves. May select one port of active pulse output
passive and one port of reactive pulse output passive
(nonpolarity). And contact with all kind of AMR system
conveniently,Complying with standard IEC 62053-31 and DIN 43864.
(Please specified when ordering)
6. Standard configuration there are far infrared and a port of
RS485 communication data, communication agreement complying with
standard DL/T645-1997. May select without function of communication
data. (Product Configuration code is NC).
7. Six LED instructions power supply state and signal of active
energy impulse and reactive energy impulse and data communications
state.
8. Automatic detection the direction of the flow of load current.
And instructions by one LED.
9. Single direction three components measure three phase four wire
active and reactive energy consumption. It is nothing with
direction of the flow of load current. Complying with standard IEC
62053-21and IEC 62053-23.
10. Standard configuration short terminals cover, may select
extension terminals cover, in order to protect to use safety.
(Product Configuration code is AF).
